Sure. Will look around for a 40G NIC system. BTW I have been testing virtio-net with a TAP device as back end.
ip tuntap add dev tap0 mode tap user $(whoami) ip link set tap0 master virbr0 ip link set dev virbr0 up ip link set dev tap0 up
which is exported into the guest as follows
-device virtio-net,netdev=network0,mac=52:55:00:d1:55:01 \ -netdev tap,id=network0,ifname=tap0,script=no,downscript=no \
But I have not run any network benchmarks on it though.
